How do I wash my Belle Rébellion?
Cold machine wash or hand wash on a gentle cycle. Rinse in cold water immediately after wear for best results. Hang to dry — avoid tumble drying and fabric softener, as both can affect the integrity of the absorbent layer over time. Do not iron.
How long do they last?
With proper care (cold wash, air dry, no fabric softener), each pair is designed to last for years — not months. This is part of what makes period lingerie such a worthwhile investment compared to the ongoing cost and environmental impact of single-use products.
Can I wear them when I'm not on my period?
Absolutely — and most women do. Belle Rébellion is designed for every day of your cycle: spotting, light bladder leakage, natural discharge, or simply because it's the most beautiful underwear in your drawer. You don't need a reason beyond wanting to wear something you love.
Can I wear them overnight?
Yes — particularly Gaia (high-waisted, great for overnight hold) and Esme (soft, gentle for nights when your body needs comfort). We recommend pairing with a menstrual cup on heavier flow nights for complete confidence.
What is OEKO-TEX 100 certification?
OEKO-TEX 100 is an independent international certification that tests every component of a textile — fabric, thread, dyes, fastenings — for harmful substances. If a product is OEKO-TEX 100 certified, it has been rigorously tested and confirmed safe for use against skin, including sensitive skin. It's one of the most credible textile safety certifications in the world.
What are PFAS and why should I care?
PFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals used in many products — including some period underwear brands — for their water-resistant properties. Emerging research links PFAS exposure to a range of health concerns, and given they sit against your most sensitive skin during your period, we believe there is simply no acceptable reason to include them. Belle Rébellion is completely PFAS-free.
What about silver particles? Are they harmful?
Silver particles (or nano-silver) are used by some period underwear brands for their antimicrobial properties. However, concerns have been raised about their environmental impact and potential effects on the skin microbiome with repeated use. We made the decision not to use them — our organic cotton lining provides a natural, breathable alternative that works without the unknowns.
How sustainable is Belle Rébellion?
Every pair is reusable and designed to last for years — replacing hundreds of single-use period products over its lifetime. Our packaging is compostable. Our fabrics are OEKO-TEX 100 certified and vegan. The average woman disposes of 100kg of period products over her lifetime — switching to Belle Rébellion is one of the most impactful small changes a woman can make for her environmental footprint.
Are your products vegan and cruelty free?
Yes — completely. No animal products or by-products are used in any component of Belle Rébellion, and nothing is tested on animals.
How can I try them risk free?
We have full faith in our beloved product - so much so we are happy for you to try your first pair risk free. Simply contact us within 30 days of purchase and we will refund your first pair if you’re not loving them, minus a $10 shipping and handling charge (if shipped within Australia). Please note: if you buy multiple pairs on your first order, we will only be able to refund one pair.
Do they actually work? Will I leak?
Yes — each pair is engineered with multiple layers of discreet, moisture-wicking, leak-proof protection and will hold up to three tampons worth of fluid. They are also also sneeze-proof, giggle-proof and middle of the month proof in addition to your period.
How do they work?
Designed with multiple layers of protection, our lingerie’s absorbency starts with a layer of Organic Cotton which sits comfortably and tox-free against your skin. This followed by two layers of highly absorbent towelling to keep you feeling dry, then a layer of breathable TPU, the final layer of protection creating highly absorbent, and comfortable lingerie.
How many hours can I wear them?
Each pair offers moderate absorbency — the equivalent of around 3 tampons. On lighter flow days, most women wear their pair all day or night. On heavier days, simply swap out for a fresh pair (your La Cachette Clutch makes this easy on the go). You can also pair with a menstrual cup or tampon for full-day coverage on your heaviest flow.
What flow levels is it suitable for?
Light to moderate flow. For heavy flow days, we recommend swapping out every few hours or pairing with a menstrual cup or disc, and using Belle Rébellion as your backup layer. Many women also wear them as overnight protection on lighter nights.
Will I be able to see it under clothes?
No. The absorbent layers don’t look bulky and sit nicely against your body. There's no visible bulk, no tell-tale panel, and no thick waistband. It looks and moves like high-end lingerie — because it is.
Is it comfortable? Does it feel like wearing a pad?
Nothing like a pad. There's no crinkle, no bulk, no awareness that anything functional is happening. The organic cotton lining feels soft against your skin, and the lace sits just like regular lingerie. The most common thing women say when they first wear it is that they forget they're on their period.
How is this different from other period underwear brands?
Most period underwear is designed to be practical first — functional, clinical, often quite basic in its aesthetic. Belle Rébellion was designed by a bridal couture designer who refused to accept that practical and beautiful were a trade-off. The lace, the gold charm, the cut — every detail was considered the same way a couture piece would be. It's also PFAS-free and silver particle-free, which many conventional period underwear brands cannot say.
Which style should I choose — Gaia, Cleo or Esme?
It comes down to your mood and your body:
Gaia — high-waisted, sculpting, powerful. Choose Gaia if you love a high-rise fit, want to feel held and supported, or tend to prefer fuller coverage.
Cleo — cheeky bikini cut, effortless, a little flirty. Choose Cleo if you prefer a more classic cut that moves with you without any extra coverage.
Esme — soft floral lace, scalloped edges, gentle. Choose Esme if you want the softest feel against your skin and love a delicate, feminine aesthetic.
